Protein Skimmer for Freshwater

The protein skimmer was design for freshwater aquaculture. Water recirculation is 30 m3 per hour. As some residual feed and fish feces already dissolved in water, mechanical filtration cannot remove it. But Protein Skimmer can remove more than 90% small suspension particle and soluble colloidal organic matter in the water. Reduce the load of biological filter.

More Flowrate of protein skimmer available:

ZH-CPS protein skimmer made of PP, not harmful for the fish. Adopt repeated N shape water and air mixed cutting technology, produce rich and exquisite bubbles, to remove the residual feeds, feces, colloidal solids, organic matter efficiently. Reduce loading of biological filter, increase water’s dissolved oxygen, and make sure a safe aquaculture water quality.

Protein Skimmer can concert with Ozone generator. Inject Ozone in to protein skimmer, use Ozone’s stronger oxidization property, oxidative damage and breakdown cell’s enzymes to kill different kinds of Pathogens quickly, and decolorize, remove smell, improve the water quality at the same time.

Comprehensive problems in use, ZH protein skimmer made below designs:

1.Discharge the foam directly by an inclined tube, no foam collection cup and no need washing water.  More water-efficient

2. The protein skimmer has emptying and blow-down valve on the bottom. Water in protein skimmer can be emptied when stop using and moving. Also can avoid encourage the growth of bacteria when long time stop using.
